Application filed June 8, 1916. Serial No. 102,422.

To all whom it may concern:

Be it known that I, DANIEL BLYDEN- BURGH, a citizen of the United States, residing at Pawtucket county of Providence, and State of Rhode lsland,-Ihaveinvented certain new and useful Improvements in Feed- Controlling Devices for Shuttles, of which the following is aspecification.

invention relates toshuttles and par I ticularlyto shuttles of the class used in looms. l g g r The object of myinvention is to provide an improved shuttle whereby the yarn will Referring now to the drawings, 1 indi- ,cates a shuttle of any usual or preferred flow freely therefrom and notdrag or otherwise injure the cloth beingwoven; it being a well know'n 'fact that irregularity in the feeding of the yarn from the shuttle fref means to control the feed of the yarn from the cop, and .to thisend I equip the shuttle with a plurality of resilient tongues 4; which bear with yielding pressure upon theyarn Qon the cop. I provide a series of tongues spaced slightly apart, as shown in the draw- .ings, so'that the cont'rollof theyarn is provided uniformly throughout the'length of the cop. It is obvious thatjthese spring tongues quently produces flaws in the cloth and'injures the selvage. A further and particular Object of my invention is to provideimproved means for insuring a uniform feed of the yarn from the cop or quill. A further and particular objectof my invention is to provide an improved threat for the shuttle whereby the yarn fed fromthe quill will feed uniformly from the shuttle. 'A

further object of my invention is toprovide an improved self threading shuttle. A fur,- ther object of my invention is to provide a yarn feed controlling device adapted to be secured to substantially any loom shuttle. Other objects will appear hereinafter.

With these objects in view my invention consists generallyin a shuttle of any ordinary or preferred form"equipped with a series of resilient tongues adapted to bear with yielding pressure against the yarn on J the cop or quill to insure uniform feed of the yarn therefrom. .My invention further consists in a yarn feed controlling device as mentioned comprising a strip adapted to be secured to i substantially any shuttle and equipped with a series of spring tongues for the purpose above mentioned. My invention further consists in providing a shuttle with an improved throat comprising a preferably metallic member having a longitudinal bore formed with a bell mouth and provided with a threading groove arranged angularly to the bore'at the outer face of said member and passing spirally into communication with the bore. My invention further consists in various details of construction and arrangement of parts all as will be fully described hereinafter and particularly pointed out in the claims.

My invention will bemore readily understood by reference to the accompanying drawings forming apart of this specification, and in which Figure l is a plan view of a shuttle embodying my invention, 1

form having the usual recess 2 for the cop 3. One feature of my invention 15 to provide may be provided on the shuttle at the 1 time the same is manufactured and that they may be secured to the shuttle in any preferred manner. However, itis, one of the objects of my invention to provide means whereby shuttles now inuse may be equipped with my-invention and tothisiend I secure the spring tongues t too. strip 5 which strip is adapted to be secured in-the recess 2 upon one of the side walls thereof and adjacent the bottom, as shown clearly in Figs. 2 and 3; The strip 5 is preferably formed of an angle member comprising a vertically disposed web 6 and a horizontal bottom flange 7. The ends of the strip are formed with perforated ears 8 to facilitate securing the strip in position, as will be readily understood. Although the tongues 4: may be formed of any preferred material, I prefer to form them of spring wire. The tongues are of suflicient length to engage the yarn on the cop intermediate the ends of the tongue, at all times, so that the ends of the tongues will not engage or interfere with the proper feeding of the yarn.

The tongues may be secured to the strip 5 in any preferredmanner but I prefer to bend them downwardly and longitudinally of the shuttle as at 9, between the web 6 and the wall of the shuttle then backwardly in the opposite direction as at 10, then into a convolution 11 and forwardly as at 12 with the extreme ends 13 bent laterally and projected into suitable apertures 1A in the web 6. \Vith this arrangement the portion 12 rests upon the flange 7 and great resiliency is given to the tongues 4, both transversely of the aXis of the cop to give the necessary pressure upon the yarn and also longitudinally of the same to give with any undue strain placed upon the same.

The throat member of the shuttle comprises a plate 15 having a block 16 on the under side thereof provided with a. longitudinal bore 17 constituting the throat. The inner end of the throat is flared as at 18 forming a bell mouth to facilitate feeding the yarn thereinto, the throat 17 itself being restricted to prevent tangled portions of the yarn from passing through the same. The outer end of the throat is also preferably formed with a bell mouth 19 as indicated in dotted lines in Fig. 2. i

To facilitate threading the yarn into the throat the throat member is formed with a threading slot 20. The outer end of this slot is angularly disposed with relation to the throat as shown clearly in Fig. 1 and passes in a spiral or twisting direction downwardly until it communicates with the throat. By this arrangement the yarn may be readily threaded into the throat and yet cannot accidentally become removed therefrom during the operation of the loom. An angularly disposed kerf 21 provides means for threading the yarn into the side or feed eye 22.

I claim l. A shuttle and cop in combination with a strip secured to the inner face of the wall of the shuttle and a plurality of spring tongues fixed to said strip and engaging the yarn on the cop substantially as described.

2. A shuttle and cop in combination with a strip secured to the inner face of the Wall of the shuttle, a plurality of transversely disposed spring tongues and a resilient connection between said tongues and said strip whereby said tongues are caused to yieldingly engage the yarn on the cop, substantially as described.

3. A yarn feed regulating attachment for shuttles comprising a strip adapted to be secured to a shuttle and a plurality of spring tongues on said strip, as and for the purpose specified.

4;. An attachment for shuttles comprising an angle bar adapted tobe secured to the inner face of the wall of the shuttle, a plurality of spring tongues and a resilient con nection between said tongues and said bar, substantially as described.

5. A shuttle and cop in combination with an angle bar secured to the inner face of the wall of a shuttle forming a longitudinally disposed pocket,' a plurality of transversely disposed spring tongues, the ends of said tongues being bent'and arranged in said pocket to form a resilient connection between the tongues and the bar, substantially as described.

6. An attachment for shuttles comprising an angle bar consisting of a vertical web and a bottom flange in combination with a plurality of laterally extending spring tongues, the inner ends of said tongues being bent into angularlydisposed portions with one of said portions resting on said flange, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
